HTML 4.x and XHTML 1.x.
This failure relates to:
Internet Explorer 6 also triggers the onclick event when a radio button with onclick receives focus; adding other event handlers (onxxx attributes) to prevent this does not work.
This document describes a failure that occurs when changing the status of a
radio button, a check box or an item in a select list causes a new window to
open. It is possible to use scripting to create an input
element that causes a change of context (submit the form, open a new page, a
new window) when the element is selected. Developers can instead use a
submit button (see G80: Providing a submit button to initiate a change of context) or clearly indicate the
expected action.
The example below fails the Success Criterion because it processes the form when a radio button is selected instead of using a submit button.
<script type="text/JavaScript"> function goToMirror(theInput) { var mirrorSite = "http://download." + theInput.value + "/"; window.open(mirrorSite); } </script> … <form name="mirror_form" id="mirror_form" action="" method="get"> <p>Please select a mirror download site:</p> <p> <input type="radio" onclick="goToMirror(this);" name="mirror" id="mirror_belnet" value="belnet.be" /> <label for="mirror_belnet">belnet (<abbr>BE</abbr>)</label><br /> <input type="radio" onclick="goToMirror(this);" name="mirror" id="mirror_surfnet" value="surfnet.nl" /> <label for="mirror_surfnet">surfnet (<abbr>NL</abbr>)</label><br /> <input type="radio" onclick="goToMirror(this);" name="mirror" id="mirror_puzzle" value="puzzle.ch" /> <label for="mirror_puzzle">puzzle (<abbr>CH</abbr>)</label><br /> <input type="radio" onclick="goToMirror(this);" name="mirror" id="mirror_voxel" value="voxel.com" /> <label for="mirror_voxel">voxel (<abbr>US</abbr>)</label><br /> </p> </form>

(none currently listed)
Find each form in a page.
For each form control that is a radio button, check box or an item in a select list, check if changing the status of the control launches a new window.
For each new window resulting from step 2, check if the user is warned in advance.
If step #3 is false, then this failure condition applies and content fails the Success Criterion.
